We design and engineer the entire range of products so there is something suitable for all weather conditions. Naturally, how cold or hot someone feels is relative to the individual. We have developed a thermal rating system, graded from ONE to FIVE to indicate the relative warmth of our products.

Products with a thermal rating of ONE are lighter weight and/or thinner and suited to warmer conditions or more energetic activities, such as running. Products with a thermal rating of FIVE are heavier weight and/or thicker, these are great for cold, extreme conditions and are suited to less-energetic, static activities, such as fishing and shooting.
